COOKING-STOVE.

To all whom it may concern Be it known that I, JAMES A. LANSING,

a citizen of the United States, residing at Scranton, in the county of Lackawanna and State of Pennsylvania, have invented certam new and useful Improvements 1n Cooking-Stoves; and I do hereby declarethe I following to be a full, clear, and exact description'of the same, reference being had to the accompanymg drawings, forming a part of this specification, and to the figures and letters of reference marked thereon. 1

This invention relates to improvements in ranges and more particularly to a device for lifting the top plate section of a range above the plane of the top ofthe range to permit ready access to the interior.

Objects of the invention are "to provide a simple and efficient 'pan'lifting device which can be installed at a very lowcost, and when installed, will not interfere with j the other parts of' therange, such as to hinder stoking of the firebox, for instance; to constructthe top plate section lifting arrangement in such manner that, when the top plate section has been elevatedabove the plane of the top of the range, it may be maintained in such elevated position without-additional support than the lifting device itself, an exceedingly simple arrangement,"permitting the range to be used as a broiler, thereby saving the cost of broiler attachments; and also to so construct the lifting device that it can be operated by a standard tool which may ber-ea'clily detached from the lifting device and applied to other uses. For instance, the lifting device maybe operated by an ordinary grate bar shaken.

which' is an accessory of every coal range, thereby saving the necessity of supplying other accessories, and reducing the cost of installation to a minimunil Other objects of theinvention will appear from the following detailed description of-a structural embodiment off the invent1onin a preferred form, and the novel features the appended claims.

thereof will be part-icularlypointed out in In the drawmgsz iFigure 1 is a perspec- Itive of one type of range provided with the present improvements, showing the top plate section in elevated positionand with Specification of Letters Patent. Application filed Apri123, 1915. Serial No. 2 3,401.

range frame.

Patented a part .of the range broken away to more clearly illustrate the parts of the pan lifting device. Fig. 2 is a top plan view of the range shown in Fig. 1 with the top plate section removed. Fig. 3 is a fragmentary frontfelevation of therange shown in Fig. 1. Fig. 4 isa detailed view of theparts of the top plate section lifting device deremovable lids 0, of usual type, is adapted to be detachably supported within frame B and for this purpose said frame B maybe provided with an opening 5, for the recep tion of thetop plate section C. The side walls of said opening I) are provided. with an inwardly projectingledge b forming a seat for the top plate section C and located a sufficient distance below the upper surface of frame B to permit the upper surface of top plate section ,C to lie flush therewith 'whenpositioned in the frame. Top plate section C is adapted to be raised from and lowered into frame B to uncover and cover the entire firebox a, and, for this purpose,

is provided with spaced rear brackets c, 0

fitting into similarly. spaced seats 6 bf located in the rear side wall of top-plate section receiving openingb. and so arranged that, when the rear brackets c, c are fitted into said seats, the top plate sectlon C will be capable of a; pivotal lifting and lowering movement along .a longitudinal axis substantially coincident withytherear wall of It will'be understood that; the above description is of the parts of a range well known in the art and is solely; for the purpose of conveying a clear understanding of the 'tached from a stove and showing the parts the top plate .sectionreceiving opening I).

improved pan lifting device, in which re- 3 side the substantial features" of the invention.

The frame B is provided with a side seat 5 extending transversely of the range along a projecting ledge Z) of the frame and located above an adjacent end plate a for instance,

of the range body. This side seat Z)? is preferably of less depth than the top-plate section receiving opening of of the frame and is sufficient width to extend beyond the outer vertical wall of adjacent end" with a side extension or plate 0 having a Said side ex-.

substantial flat under surface. tension correspondsin outline with seat I b and is approximately the same depth to enable said extension to fit nicely within the seat and lie flush with the upper surface of frameB, when the pan is in lowered position. Y

' The pan lifting arm D is adapted to pro ject through transverse slot b into engagement with the flat under face of plate 0 when lifting top plate section'C. As shown, lifting arm D is preferably curved and is provided with a substantially flat lifting face d, engageable with the flat under face 'of plate '0 and so inclined with respect to the lifting arm that when the arm and top plate section are in elevated position, said face (Z lies in a plane substantially parallel withthe plane of the top plate section. In

this manner, the lifting arm provides a flat supporting surface for the top plate section when in elevated position, which prevents slipping of the top plate section and probable breaking of the parts of the range. The liftin arm D is carried by a rotatable support d having a circular socket (Z fitting over a circular lug (Z which projects from the outer wall of end plate a and forms a fixed axis on which support d and lifting arm D oscillate. Projecting outwardly from the support d and substantially at right angles from the surface of 'end'plate a is a squared or otherwise polysided shank (Z engageable with a suitable detachable tool, such as a grate bar shaker, for instance, when it is desired to lift or lower the top plate section. The retaining member for the support comprises a segmental journal (Z and a plated positioned against asidestop (Z and a bottom stop (Z both projecting from the outer wall of end plate a. Said plate d will be securely fastened to plate a at e and stops d d will prevent ,sllpping.

',prov1ded with an upper abutment e and a 80 Segmental journal d is lower abutment 6 which abutments cooperatewith abutting surfaces 6 0 carried by rotatable support 03 and form stops for limiting the oscillatory movement of the support and in turn the lifting arm D. Gooperating lower stops e 6 limit the lowering movement, just after the rotatable support has passed center. In this manner,

. the lifting arm D, itself forms a support for maintaining the top plate section 0 in elevated positlon. Such an arrangement 1s of great ut1l1ty for it permits the range to be, used as a broiler without incurring the cost of installing expensive broiler attachments. i

It will be noted that all the parts of the improved lifting device are mounted exteriorly of the firebox, so that not only is a much longer life imparted to the parts themselves, but also they do not in any manner interfere with the .other parts of the rangenor with stoln'ng of the firebox. The arrangement is so simple that by merely applying a tool F to the shank d and oscillating support 03 the lifting arm D will lift the top plate section 0 and support it securely in elevated position against slipping, on supporting surface d. The top plate section may be lowered by reapplyin'g .under surface of the top plate sectionto elevate it above the plane of the stove body, I

a stop for limiting the lifting movement of said arm, and means for throwing said arm past center into engagement with said stop to lift. the top plate section into extreme elevated position and support said section in such position by the engagement of the lifting arm with its flat under surface.

In a range, the combination of the said arm and projecting substantially at 10 range body, a top plate section mounted right angles from the plane of the stove 5 thereon for pivotal movement, a lifting arm body, said shank being adapted for cooperapivotally mounted on the stove body and ention with a detachable arm actuating lever. gageable with the top plate section to lift JAMES A.
